To aZZ 'whom t may concer/n: v Be Ait known that l, FREDERIC E. BER- TRAND, a citizen fof vthe United States, residing .at;Lynn, inthe county or Essex and State or-Massachusetts, haveinvented cer.-r

,tain. new and useful Improvementsvin Thread-Waxing Devices; and I doV hereby 20 provide a novel and improved stripping device ofthis typeI which is simple inrconstruction and eiiicient and economical-in use. W ith'this object4 lin view alfeaturevor the present Vinvention contemplates the .provision in a. thread waxing'devioe or a stripping devicecomprising. two cooperating oppositely `disposed stripping members having overlapping portions forming opposite walls of `a passage for 'thek thread kwhich passage -is arranged vtransverse to the plane of said overlapping portions.; Preferably, the stripping vmembers are equilateral and v have v corner portions thereooverlapping to form-the threadpassageso that when one set offcorners become worn, othercorners or the stripping members maybe used. ln the pre;- ferredy embodiment of the invention' the stripping members are triangular 1in shape, and means kof. simple construction is-pro- 40 ,vided for removably securing the stripping members in place and `for relatively Vadjusting the stripping members `to regulate the sizeof the threadpassage, 'As illustrated in -the accompanying dra'vvings,.the stripping `device comprises two spirally ormedstripping'v members, the;` coils or` which f' are triangular in shape and arranged one above the other, and the adjacent corners vor which are arranged in overlapping relation toj'orm ar y relatively long thread passage. l

Other vfeatures of the presentvinvention comprise certain constructions, arrangements,fand combinationsfof parts herein- THREAD-waxing# DEVICE.

after described and claimed,'the'advantages of which will be obviousft'o those skilled' in theart, f 1 g x s. l i -The `several 1features of the present "inven- Vtion will bev clearlyunderstood from' the' foli lowing description and accompanying draw*- ings inwhich:

is closed bya cover 12, andV-withinthe wax pot is mounted a lthread truck V14 overwhic'h. the 4thread passes. Asthe thread is `being drawn from thewaxing kdevice'bythe thread handling devices yorthe sewing machine,I it

The 'thread Waxing device as' interrata it the drawings is particularly adapted" for usel passes through a stripping device 'which removes the superfluous waxv vfrom the thread. Asillustrated in the drawings, the stripping device comprises two spirallyl formed strip:- ping "members V16 of i spring 1 wire, the coils or each of which are triangular inl shape and arranged one above the other. TheV stripping members, when inoperative position,

are positioned sol that their inner-'cornersl are arranged in overlapping `relation "to -form a passagefor the thread between-them Vas shown in Figs'Q and 4f; 'The stripping members are .mounted within a housingor chamber 18, the bottom wall or which is provided with :an aperture 20 through ,which the `thread `passes to .the stripping device.

The stripping members rest upon the ,bottoni wall4 of the chamber 18 "and ytheir" rforward sides engage the forward. wall E22 ofthe chamber whichy wallprojects inwardlyand is V-shaped to iit the kforward sides of the stripping: members.` The stripping members are held inlplace against the* wall 22 of the chamber byV means of a clamping bloclr 75 i tion constitutes a division. -Thedevice comv kprises a wax pot 10, the vvupper endoffwhich 24, the forward face of which is ll-shaped to engage the rear sides of the stripping members.l The clamping block 2ak is adjustable toward and from the stripping members by means of a screw 26 threaded through an aperture, in the rear wall of the chamber 18 and having its inner end engaging a socket in the clamping block. Vith this construction it will be seen that when one set of corners of the stripping members have become worn, the stripping members mayl be repositioned so that a fresh set of corners may be used, and when.` these iny turn become f worn, the remaining set of corners may be used. Also, by adjustment of the clamping block 24, the stripping members may be relatively adjusted to regulate the passage for the thread through the stripping device so as to leave any desired amount of wax on the thread.
